The second edition of The Biomarker Guide is a fully updated and expanded version of this essential reference. Now in two volumes, it provides a comprehensive account of the role that biomarker technology plays both in petroleum exploration and in understanding Earth history and processes. Biomarkers and Isotopes in Petroleum Exploration and Earth History itemizes parameters used to genetically correlate petroleum and interpret thermal maturity and extent of biodegradation. It documents most known petroleum systems by geologic age throughout Earth history. The Biomarker Guide is an invaluable resource for geologists, petroleum geochemists, biogeochemists, and environmental scientists.
